BE AWARE: welcome to post a nice screenshot to show what can be done here. But please don’t ask question or post issues here. See support section in the Venus OS Large manual for that.
As some of you know, something new is in the works, called "Venus OS large". This post is intented to start getting a large audience for it, as well as to recruite more help in further developing it.
This story is a bit longer than I usually type, here we go:
Node-RED is a tool for connecting hardware devices, APIs and online services. It provides a browser-based editor that makes it easy to wire together flows. With it, one can for example program something relatively simple such as a relay to open or close based on a temperature measurement. As well as make far more complex algorithms, tying voltage, current, power or other readings and other data available from Venus OS or elsewhere together with outputs such as relays or control points of the Victron system. All without having to write real source code.
Also Node-RED features a fully customisable dashboard, viewable in a webbrowser - both locally and remotely, via the VRM Servers.
Signal K server is aimed for yachts, and multiplexes data from NMEA0183, NMEA 2000, Signal K and other sensor inputs. It makes all that data available for Apps, such as WilhelmSK, a highly customizable boat instrument display. The Sailing with Signal K blogpost on our website is a great read for more information and ideas.
Customisation & automation without needing to be a software developer
The value of above is that now you can self configure and customise your GX Device to do many of the things asked for here. And doing so without having to posses software developer skills. It will require patience, time and to be not too afraid of trying things.
Its really extremely powerful and I'm super excited about the possibilities.
Documentation & how to install
Venus OS Large is available for the Cerbo GX, Venus GX, MultiPlus-II GX and EasySolar-II GX as well as the RaspberryPi3 and RaspberryPi 4.
Want to help?
There are a few ways to help. First of all by simply installing and using it; and reporting any issues, or just that you're happily using it and what you are using it for.
The other is by helping others here on the Modifications section on Community. There is and will be no official support for Venus OS Large. Instead, we are referring users to turn here, the Modifications Space on Victron Community. You can help by answering questions.
Next, there is developing and improving the documentation; The manual needs further development, also the nodes and available measurements will need detailing and documenting, examples, screenshots, videos, it will all help adoptation and getting the best out of this. And we'll need more help for all of that that.
Lastly I am looking for help in development and support. First of all to further develop and support the Victron integration into Node-RED, ie. the node-red-contrib-victron package. Which will require nodejs experience, Linux experience, and preferably also experience with Victron products; ideally you'd be following and taking part of the discussions here on Community, (remotely-) debugging issues as well as suggesting and implementing new functionality in the said package.
Besides the node-red package, also the integration of Node-RED and Signal K in Venus OS needs to be maintained. Which requires a different skillset: deep experience and knowledge of Linux, but also the Open Embedded build system.
I can type a whole lot more about this, but have to stop now. Have a good Sunday! And if you have examples, or questions or comments, welcome to put them below.
